China's first magnetostrictive guided wave detector successfully developed

According to a report from CCTV. After thousands of experiments in four years, China's first magnetostrictive guided wave detector was successfully developed at Zhejiang University. The instrument applies ultrasound guided wave technology to the non-destructive testing of steel rails, iron cables, and rails, and has the advantages of large detection range, wide application range, and low detection cost.

Rutile Titanium Dioxide

Rutile Titanium Dioxide is used in coatings, plastics, paper, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.

At the same time, titanium dioxide has a good UV shielding effect, and is often incorporated into textile fibers as a sunscreen. Ultra-fine titanium dioxide powder is also added to sunscreen cream to make sunscreen cosmetics.

Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has the functions of strengthening, anti-aging and filling. Titanium dioxide is added to white and colored rubber products. It is resistant to sunlight under sunlight, does not crack, does not change color, has high elongation and is acid and alkali resistant. Titanium dioxide for rubber is mainly used in car tires, rubber shoes, rubber flooring, gloves, sports equipment, etc., generally anatase type. However, when used in the production of automobile tires, a certain amount of rutile products are often added to enhance the anti-ozone and anti-ultraviolet capabilities.

Titanium dioxide is also widely used in cosmetics. Because titanium dioxide is non-toxic and far superior to lead white, almost all kinds of fragrant powder use titanium dioxide instead of lead white and zinc white. You only need to add 5%-8% of titanium dioxide to the fragrance powder to get a permanent white color, making the fragrance smoother, having adhesion, absorption and hiding power. In gouache and cold cream, titanium dioxide can weaken the greasy and transparent feeling. Titanium dioxide can also be used in various other spices, sunscreens, soap flakes, white soap and toothpaste.
The glaze made of titanium dioxide has strong transparency, low quality, strong impact resistance, good mechanical properties, bright colors, and is not easy to be polluted. Titanium dioxide for food and medicine is titanium dioxide with high purity, low heavy metal content and strong hiding power.
